Its trademark is its beautiful, profuse coat, but the intelligent and agile Old English Sheepdog can easily complete any demanding task asked of him by a shepherd or drover. Square in build and possessing great strength, the Old English Sheepdog enjoys working and is seen in the conformation, obedience, agility and herding rings today with their characteristic shuffling gait. His coat, which serves as insulation, can be any shade of gray, grizzle, blue or blue merle.
